What is the main benefit of this larger intercooler core?

The 68mm-thick bar-and-plate intercooler core is 70-percent thicker than stock, allowing it to cool the intake air more effectively. This results in denser air charge for the engine, which can improve performance and towing capability.

Does this kit include everything needed for installation?

The kit includes the performance intercooler, hot-side and cold-side intercooler pipes, and DuraCore boots with T-bolt clamps. It is designed for a direct fit, utilizing factory mounting locations and quick-disconnect fittings.

Can I add aftermarket sensors or water/meth injection to this kit?

Yes, the aluminum piping includes three bungs that can be drilled and tapped. This allows for the installation of additional sensors or a water/meth injection system for further tuning and performance enhancements.

Product Details

The 6.6L Duramax L5P engine in your 2017-2019 Chevrolet Silverado 2500 HD or 3500 HD, or GMC Sierra 2500 HD or 3500 HD, is a powerful piece of machinery, but its intercooler system can be a bottleneck. This Mishimoto Performance Intercooler Kit addresses that directly with a massive 68mm thick bar-and-plate core, which is 70-percent thicker than the stock unit. This larger core, combined with cast-aluminum end tanks featuring improved inlet and outlet designs, significantly reduces restriction by up to 64-percent. This means cooler, denser air making its way to your engine, which is crucial for performance, especially when towing heavy loads or under demanding conditions.

Beyond the core, the kit includes 3.0-inch mandrel-bent aluminum piping designed to replace the restrictive stock resonator and improve flow by up to 55-percent. Mishimoto uses DuraCore™ boots and constant-tension T-bolt clamps for a solid connection, and the piping is designed to fit like stock, utilizing CNC-machined quick-disconnect fittings and mounting locations for factory sensors and harnesses. Plus, there are three bungs included that you can tap for additional sensors or a water/meth injection system, offering flexibility for further tuning. This kit is a direct fit for your truck and is a substantial upgrade whether your truck is mostly stock or heavily modified.

This kit comes complete with the performance intercooler, hot-side and cold-side intercooler pipes, and the necessary DuraCore boots. It's a well-built system designed for years of reliable service, helping your Duramax engine perform at its best. Keep in mind that this kit is not CARB approved and cannot be shipped to California.
